How to Make Sweet Potato Cake
1. Prepare the Sweet Potatoes
Peel and cube sweet potatoes. Boil or steam until tender (about 15–20 minutes). Mash until smooth, no large chunks, and allow to cool slightly.
2. Preheat & Prepare Pan
Preheat your oven to 350°F / 175°C. Grease your cake pan and lightly dust with flour, or line with parchment paper.
3. Mix Dry Ingredients
In a medium bowl, whisk together flour, baking powder, baking soda, salt, cinnamon, nutmeg, and ginger. Set aside.
4. Cream Wet Ingredients
In a large bowl, beat oil (or melted butter) and brown sugar until well combined. Add eggs one at a time, then stir in vanilla extract.
5. Combine Wet & Dry
Gradually fold dry ingredients into the wet mixture. Stir in mashed sweet potatoes and milk until smooth. The batter should be thick but pourable.
6. Bake the Cake
Pour batter into your prepared pan and smooth the top. Bake for 50–60 minutes, or until a toothpick inserted in the center comes out clean.
Pro Tip: If the top browns too quickly, tent loosely with foil halfway through baking.
7. Cool & Frost (Optional)
Allow the cake to cool in the pan for 10–15 minutes before transferring to a cooling rack.
Optional Cream Cheese Glaze: Beat cream cheese, butter, powdered sugar, vanilla, and milk until smooth. Spread over cooled cake for a tangy-sweet finish.
Tips for Perfect Sweet Potato Cake
Use cooked sweet potatoes — roasting adds deeper flavor, but boiling is quicker.
Room temperature ingredients — helps with even mixing and texture.
Don’t overmix — This keeps the cake light and fluffy.
Spice balance — adjust cinnamon, nutmeg, or ginger to taste for a personal touch.
Storage — store covered at room temperature for 2–3 days or refrigerate for up to a week.
